I've got these! They're awesome! I just read this post and did some modification on mine. I went and bought some 6 mm utility climbing cord and replaced the short ones that come with these. Now using the door gym I can adjust the height of these for dips, pull-ups and push-ups. Dips are tricky!

yeah rock rings kick ass, thanks for the reminder. I have added a link to my products page they are way cheaper than normal rings as well.
